WASHING MACHIN E.

Application filed February 19, 1925. Serial No. 10,810.

The object of my invention is to provide a washing machine of simple, durable and inexpensive construction.

A further object is to provide in a washing a machine an improved tub which is leak proof and which will not dry out, and at the same time is capable of retaining hot water for a parts of the device, whereby the objects con-- 20 templated are attained, as hereinafter more fully set forth, pointed out in my claim, and illustrated in; the accompanying drawings, in which:

Figure 1 is a side elevation of my improved as washing machine.

- Figure 6 is a detail sectional view taken on the line 6-6 of Figure 1.

Figure 7 is an enlarged detail sectional view taken on the line 77 of. Figure 1.

Fig. 8 is a artial vertical cross-section 4a of the wash tu My improved washing machine comprises a supporting frame 10 which has legs formed of vertically arranged angle irons 11. The top ends of said angle irons are connected by means of horizontally arranged anglesv 12. The lower ends of the legs 10 are provided with horizontally arranged members 13. One

of the transversely arranged members 12 is provided with a pair of angle brackets le to which members 15 are pivotally mounted, the free ends of which are connected b a cross member 16. This providesan auxillary rack which may be folded to a vertical position, as

- indicated by dotted lines in Figure 4. The rack is supported in a horizontal position by means of a brace 17, one end of which is pivotally connected at 18 to the central portion of the member 16. The member 17 extends downwardly and inwardly and has its lower end provided with an annular portion 19 which is provided with a slot 20.

Mounted between the frame members 12 and 13 is a vertically arranged rod 21 which extends through the slot 20 of themember 17 and provides a guide for the lower end of said member 17 for retaining the lower end of the member 17 against lateral movement when the rack is in an elevated position. When the said rack is in a horizontal position, the lower end of the brace 17 will rest against the lower end of the rod 21 and retain the rack against downward movement. By this arrangement I have provided a folding rack which is adapated to be quickly moved, to a vertical position with the upper end .of the rack inclined sligh'tly inwardly, the said rack being limited against inward movement by the outer end of the slot 20 engaging the rod 21. Thus it will beseen I-have provided a rack which may be moved to either a folded or operative position, and which may be retained in either of said positions without the use of any locking device which might accidentally come loose.

Mounted on the top of the members 12 I have provided a tub 22 which comprises a bottom member 23 constructed in the form of a disk and of some stron heat insulating material such as wood. N ounted on top of the bottom member 23 I have provided a cylindrical inner lining 24 formed of sheet metal, said lining includin side members and a bottom member 25. 11 order to prevent rapid radiation of heat I have provided an outer wall member 26 which may also be made of sheet metal. The wall 26 is of a larger diameter than the wall 24;, so that an air space 27 may be provided between the members 523 and 24:. The member 24 is somewhat smaller annular flange 33 which is designed to be mounted between the upper ends of the members 24 and 26. The side portions of the flange 33 are somewhat tapered.

For retaining the frame member in posi-- tion I have provided a series of vertically arranged stay rods 34 which extend through the cover member and between the members 24 and 26 and through the outer edge of the member 23. The lower ends of said stay rods are provided with nuts 35 by means of which the cover may be clamped to the upper edge of the member 24. The member 26 is formed of a single sheet of metal which is folded around the outer edge of the member 23 and against the outer edge of the flange 33, the adjacent ends of said member being provided with oppositely curved portions 36, as clearly shown in Figure 7.

The said members 36 are provided with tapering edges and are designed to receive a keeper 37 formed of sheet metal and provided with folded portions 38 designed to coact with the members 36. This member 37 is also tapered so that after the member 26 has been placed in position around the tub with the members 36 adjacent, the member 37 may be slid longitudinally with the said members 36 and provide means for drawing the ends ofthe member 26 together and for locking them in said position. This provides means whereby the outer member 26 may be easily and quickly removed if necessary for soldering or repairing the inner member 24.

Thus it will be seen that I have provided a tub which is made water tight and which will not dry out, and at the same time prevent a large amount of radiation due to the fact that a dead air space 27 is provided between the members 24 and 26, the wooden bottom 23 serving to form a rigid support for the sheet metal bottom 25 and also to provide a heat insulator at the bottom of thejtub.

Mounted above the member 30 I have provided a gear housing 39, while the member 31 is provided with a hinge member 40. The inner end of the gear housing 39 is also provided with a hinge member 41. Said members 40 and 41 are designed to pivotally support the cover 42, the center of which is provided with a downwardly extending dolly shaft 43, the lower end of which is designed to carry a dolly 44. The upper end of the dolly shaft 43. has a pinion gear 45 in mesh with an intermediate gear 46 which is pivotally mounted to the cover 42 by means of a pivot pin 47. The said pin 47 is mounted in a line parallel with the pivot axis of the cover 42 and extends through the dolly shaft 43. A rack gear 48 is in mesh with the gear 46 and is also pivotally mounted in alinement with the members 43 and 47 by means of a pivot 49 which is mounted in the gear casing 39. The pitch lines of the gears 46 and 48 are substantially above the inner edge of the member 30, so that as the cover 42 is the same, providing means whereby the dolly 43 will be automatically thrown out of engagement with the gear 48 each time the cover 42 is raised to an open position.

For oscillating the rack 48 I have provided beneath the outer end of the gear casing 39 a gear casing 50 which is provided with a vertically arranged sleeve 51 connecting with the gear casing 39. The sleeve 51 is provided with a vertically arranged shaft 52 which has an eccentric 53 mounted in the outer end of the casing 39. The said eccentric carries an eccentric rod 54, the free end of which connects the rack 48, so that as the shaft 52 is rotated, said rack 48 will be oscillated.

The lower endof the shaft 52 is provided with a beveled gear 53 designed to mesh with a bevel pinion 54 mounted on the horizontally arranged shaft 55. The pinion 54 is provided with a spur gear 56 designed to mesh with a pinion 57 on a shaft 58. Said shaft 58 is designed to carry a belt wheel 59 driven from an electric motor 60 through the belt 61. The gear casing 50 is formed comparatively tight so that it may be filled with heavy grease. The motor 60 is mounted on a base 62 which has its inner edge pivotally mounted on a shaft 63 in such a manner that the weight of the motor 60 will cause the belt 61 to be always retained in a taut condition.

Thus it will be seen that if the motor 60 is operated the belt pulley 59 will be rotated, which will cause the vertically arranged shaft 52 to be rotated through the pinion 57, the

gear 36, the pinion 54 and the gear 53. The

eccentric 53 will cause the rack 48 to oscillate, which in turn will impart an oscillatory movement to the dolly shaft 43. It will be seen that when the rack 48 is being oscillated that there will be a tendency for the cover 42 to also be oscillated, and for the gear 46 and said rack to operate. This I have overcome by providing in the upper portion of the casing 39 an up,- wardly projecting pin 65. The gears 45 and 46 are provided with a housing 66 which has an outwardly projecting lug 67 provided with an opening 68. These parts are so arranged that as the cover 42 is closed, the opening 68 will pass over the pin 65, thereby providing a rigid connection between the housing 66 and the housing 39, while the cover is in a closed 7 position.

Thus it will be seen I have provided a washing machine of simple, durable and inexpensive construction, in which all of the gear devices are enclosed so that they may be freely lubricated, and at the same time prevent the lubricant from getting onto the clothes being washed.

I have also provided an improved tub which may be I formed principally of sheet metal and which will retain the heat a great deal longer than can be accomplished by a tub formed of a single wall of sheet metal, this metal tubs.

being the main objection to the ordinary sheet The tub is so constructed that it may be easily and quickly taken apart for repairs if so desired.

I claim -as my invention In a washing machine, the combination of a base member, an open top tub mounted on the base member, the periphery of the base member extending beyond the tub, a cover for the tub having two downwardly projecting flanges thereon spaced apart from each other, the inner one being designed to engage the outer edge of the top of the tub, a heat retaining wall member formed of sheet metal and cylindrical in form and of a diameter considerably greater than that of the tub, and having its lower edge resting against the periphery of the base and its top edge engaging the outer one of said downwardly extending flanges on the cover, the upright walls of the tub and of the heat retaining wall and the portions of the base and cover members arranged between these walls being substantially a1r tight to form a dead air space, and bolts extended through the'cover member and the base member and lying wholly in the space between the tub and the heat retaining wall member for firmly securing the cover member to the tub and for holding the heat retaining wall member in position.
